Description

Technical Field

[0001] The utility model relates to the field of capsule filling machines in pharmaceutical machinery, and particularly to a discharging device for a capsule machine. Background Art

[0002] At present, the existing discharging structures usually have the following forms: one is a double-row discharging structure, which only uses compressed air to discharge two rows of capsules simultaneously; one is a single-row discharging structure, which uses compressed air and an inclined baffle to assist in discharging at the same time. The capsules are first pushed upward and then hit the inclined surface of the baffle, so as to fall outward, and then supplemented by a blowing discharging method, so that the capsules are sent out under the action of lateral blowing; one is that the capsules are pushed into the discharging guide groove and then sent out along the notch under the action of a fork. In this structural form, there is sometimes a structure that sweeps the powder on the surface of the capsules through a silica gel pad when the capsules are pushed out.

[0003] The double-row discharging structure needs to push out two rows of capsules at one time. After the capsules are pushed out, the outer-row capsules will block the inner-row capsules from being discharged. Therefore, greater external force is needed for assistance. If the air volume is small, discharging cannot be achieved, but if the air volume is large, it is easy to cause dust to fly after blowing, polluting the production workshop environment; in the existing single-row discharging structure, the direct contact between the capsules and the baffle or the guide groove is likely to cause scratches on the capsule shell, affecting the appearance and quality of the finished products. Moreover, the compressed air is only connected to the baffle by a hose for blowing, which increases the cleaning difficulty. In addition, due to the overall open structure of the discharging structure, blowing will blow the dust away, polluting the workshop environment and causing great obstacles to the subsequent site cleaning; in the structure where the capsules are pushed into the discharging guide groove, the direct contact between the capsules and the guide groove is likely to cause scratches on the capsule shell, affecting the appearance and quality of the finished products. Although using a silica gel pad can reduce the powder on the surface of the capsules and avoid dust flying, it will cause the powder to directly fall on the push rod and the push plate. As time goes by, the powder will quickly fill the discharging station, and cleaning and replacement are time-consuming and laborious. Moreover, the silica gel pad has a short service life and needs to be replaced regularly, which not only increases the cost but also is time-consuming and laborious. In addition, the existing blowing structure usually uses a hose and a tracheal joint to supply air. On the one hand, the messy trachea will affect the aesthetic appearance, and on the other hand, powder will accumulate in the gap between the tracheal joint and the trachea, which is difficult to remove and affects the site cleaning work after production. Summary of the Utility Model

[0004] In view of this, the utility model aims to provide a capsule discharging device to solve the problems existing in the old structure, such as easy scratching of capsules, difficult disassembly, cleaning and adjustment, and easy pollution of the production environment by blowing, so as to meet the requirements of high-quality and high-efficiency production.

[0005] To achieve the above object, the technical solution of the utility model is realized as follows: A discharging device of a capsule machine, comprising a hand-tightening nut, a first discharging upper plate, a second discharging upper plate, a discharging bottom plate, a discharging shaft, a discharging port and an adjusting gasket. The upper end of the discharging shaft sequentially passes through the discharging bottom plate, the second discharging upper plate and the first discharging upper plate, and then is threadedly connected with the hand-tightening nut. At the same time, the first discharging upper plate and the second discharging upper plate are detachably connected. The discharging port is installed at the open end of the discharging bottom plate, and a plurality of adjusting gaskets are installed at the shoulder position in the middle of the discharging shaft.

[0006] Further, the first discharging upper plate is provided with a first mounting hole and a first shaft hole; the second discharging upper plate includes an upper plate main body, a second shaft hole, a boss, a first groove, a second groove, a second mounting hole and an air outlet. The upper plate main body is provided with a second shaft hole and a second mounting hole. The upper end surface of the upper plate main body is provided with a first groove and a second groove. One end of the first groove communicates with the second shaft hole, and the other end communicates with the second groove. The lower end surface of the upper plate main body is provided with a plurality of bosses. The bosses are provided with ventilation pore channels, and the ventilation pore channels of all the bosses communicate with the second groove. An air outlet is horizontally arranged on the boss, and the air outlet communicates with the ventilation pore channel of the boss.

[0007] Further, the first mounting hole is a threaded hole. After the first discharging upper plate and the second discharging upper plate are installed together, the first mounting hole and the second mounting hole can form a complete mounting hole, and the two are coaxially arranged.

[0008] Further, the discharging bottom plate includes a bottom plate main body, a partition plate, a baffle, a passage hole and a third shaft hole. The bottom plate main body is provided with a partition plate and a third shaft hole. The partition plate divides the bottom plate main body into two discharging areas. A plurality of passage holes are arranged at the edge position of the bottom plate main body, and a baffle is arranged between two adjacent passage holes.

[0009] Further, after the second discharging upper plate and the discharging bottom plate are installed together, one boss corresponds to one passage hole, and the boss is arranged obliquely above the passage hole.

[0010] Further, the top end of the discharging shaft is provided with a threaded structure matching the hand-tightening nut. Four mutually communicating air holes are arranged at a position close to the top end of the discharging shaft. At the same time, an air path structure is arranged inside the discharging shaft, and the air path structure communicates with the air holes.

[0011] Further, O-ring grooves are respectively arranged in the first shaft hole and the second shaft hole, and sealing rings are respectively installed in the two O-ring grooves.

[0012] Compared with the prior art, the discharging device of the capsule of the utility model has the following advantages:

[0013] (1) The capsule discharging device of the present utility model can operate only by compressed air and does not require too much compressed air force. It not only effectively avoids scratching of the capsules, but also the discharging process is relatively enclosed, and it is not easy to generate the problem of dust flying.

[0014] (2) There are two air outlets, one above the other, on the convex platform of the present utility model, which can effectively ensure that the capsules can only be discharged in the specified direction. And because each capsule has two air outlets, one above and one below, to assist in discharging, it will not tilt in advance during the discharging process and get stuck in the through holes of the discharging bottom plate, nor will there be a risk of the capsules falling back. At the same time, since there is no structure such as a stop block in direct contact with the capsules during the discharging process, the capsules are effectively prevented from being scratched.

[0015] (3) The complete air path formed by the first discharging upper plate and the second discharging upper plate. When air flows in, the air outlets provided on the convex platform are responsible for blowing out the air flow. One end of the first groove is connected to the middle position of the second groove, so that the single-side air path enters from the middle position, which can minimize the air volume difference of each air outlet and effectively balance the force of blowing out the capsules at each position.

[0016] (4) By increasing or decreasing the adjusting gaskets, adding or removing a part of the adjusting gaskets between the discharging bottom plate and the discharging shaft, the height of the overall discharging structure can be adjusted to match various types of capsule molds, without the need to use a feeler gauge and a wrench for adjustment, which is convenient and fast.

[0017] (5) After the present utility model blows out the capsules, although dust will also be generated inside, through the beam-forming structure at the discharging port, the capsules and the blown powder can be gathered together and discharged. At this time, most of the powder has settled, and then by connecting to a capsule polishing machine, the situation of dust flying can be minimized to the greatest extent, protecting the cleanliness of the workshop environment, and there are not so many sanitary dead corners, which is convenient for subsequent cleaning.

[0018] (6) All the air paths of the present utility model are hidden inside the parts, so no exposed air pipes and pipe joints can be seen from the outside. The air source directly passes through the inside of the discharging shaft to the hidden air path formed by the first discharging upper plate and the second discharging upper plate. After hiding the air path, the discharging shaft not only serves as a supporting and positioning structure, but also can avoid using additional air pipes to transmit the air source, effectively saving the table space and facilitating the cleaning work of the staff after production.

[0038] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0039] The present utility model will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0040] Such as Figures 1-12As shown in the figure, the utility model is a discharging device of a capsule machine, which includes a hand-tightening nut 1, a first discharging upper plate 2, a second discharging upper plate 3, a discharging bottom plate 4, a discharging shaft 5, a discharging port 6 and an adjusting gasket 7. The upper end of the discharging shaft 5 sequentially passes through the discharging bottom plate 4, the second discharging upper plate 3 and the first discharging upper plate 2, and then is threadedly connected with the hand-tightening nut 1. The lower ends of two discharging shafts 5 are respectively connected with an air pipe, and the other end of the air pipe is connected with an air source. At the same time, a solenoid valve is installed on the air pipe. The solenoid valve can control the opening or closing of the air source, and the solenoid valve can connect the air path when the capsule is pushed out according to the running speed of the discharging device, that is, the solenoid valve can control the intermittent connection of the air source of compressed air to realize intermittent air supply. The air pipe, the air source and the solenoid valve are all prior arts. The first discharging upper plate 2 and the second discharging upper plate 3 are detachably connected, and the discharging port 6 is detachably installed at the open end of the discharging bottom plate 4. The discharging port 6 has a structure with a large inlet and a small outlet. After the capsule is blown out, it is collected and summarized through the discharging port 6, which can summarize the two groups of separately discharged capsules into one place, facilitating subsequent collection and largely avoiding the damage of dust to the workshop environment. A plurality of adjusting gaskets 7 are installed at the middle shaft shoulder position of the discharging shaft 5. The adjusting gaskets 7 are installed between the discharging bottom plate 4 and the discharging shaft 5. By changing the height of the adjusting gaskets 7 according to different capsule models, the discharging operation of different models of capsules can be realized, so as to meet the discharging requirements of various models of capsules. Specifically, when the size of the capsule to be discharged is reduced compared with before, the height of the capsule cap also decreases accordingly. Therefore, the thickness of the upper module in the corresponding preparation module 9 will be reduced. At this time, if the height of the discharging bottom plate 4 does not change, it will cause the capsule to not be able to pass through the through hole 44 of the discharging bottom plate 4 due to insufficient pushing length. Therefore, it is necessary to remove the adjusting gaskets 7 installed between the two discharging shafts 5 and the plane of the discharging bottom plate 4. The number of removed gaskets on both sides is the same. The specific number is actually determined according to the height of the discharging bottom plate 4 from the upper surface of the upper module in the preparation module 9, generally about 1 mm from the upper surface of the upper module. The removed adjusting gaskets 7 can be installed under the hand-tightening nut 1 to prevent the adjusting gaskets 7 from being lost. After removing the adjusting gaskets 7, the upper end of the discharging shaft 5 is sequentially passed through the discharging bottom plate 4, the second discharging upper plate 3 and the first discharging upper plate 2 again, and then is threadedly connected with the hand-tightening nut 1, so as to realize the fixation of the first discharging upper plate 2, the second discharging upper plate 3, the discharging bottom plate 4 and the discharging shaft 5. This operation only uses two hand-tightening nuts 1 for fixation and can be disassembled and assembled without the aid of other tools; similarly, when it is necessary to replace a capsule with a larger size, operate in the reverse order according to this process, and replace the spare adjusting gaskets 7 installed under the hand-tightening nut 1 into the gap between the discharging shaft 5 and the plane of the discharging bottom plate 4. The upper module and the capsule are both prior arts.

[0041] The first discharge upper plate 2 is provided with a first mounting hole 21 and a first shaft hole 22; the second discharge upper plate 3 includes an upper plate main body 31, a second shaft hole 32, a boss 33, a first groove 34, a second groove 35, a second mounting hole 36 and an air outlet 37. The upper plate main body 31 is provided with a second shaft hole 32 and a second mounting hole 36. The upper end surface of the upper plate main body 31 is provided with a first groove 34 and a second groove 35. One end of the first groove 34 communicates with the second shaft hole 32, and the other end communicates with the second groove 35. The lower end surface of the upper plate main body 31 is provided with a plurality of bosses 33. An air vent passage 38 is provided in the boss 33, and the air vent passages 38 of all the bosses 33 communicate with the second groove 35. An air outlet 37 is horizontally provided on the boss 33, and the air outlet 37 communicates with the air vent passage 38 of the boss 33. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0042] The first mounting hole 21 is a threaded hole. After the first discharge upper plate 2 and the second discharge upper plate 3 are installed together, the first mounting hole 21 and the second mounting hole 36 can form a complete mounting hole, and the two are coaxially arranged. At this time, the detachable installation of the first discharge upper plate 2 and the second discharge upper plate 3 can be realized by bolt connection, which is convenient and fast. After the first discharge upper plate 2 and the second discharge upper plate 3 are combined and installed, the lower surface of the first discharge upper plate 2 fits with the upper surface of the second discharge upper plate 3. The first discharge upper plate 2 can block the upper openings of the second shaft hole 32, the first groove 34 and the second groove 35 of the second discharge upper plate 3, so as to jointly form a complete hidden air path, and the hidden air path is connected to each boss 33. In the present invention, all air paths are hidden inside the parts, so no exposed air pipes and air pipe joints can be seen from the appearance. The air source directly passes through the inside of the discharge shaft 5 to the hidden air path formed by the first discharge upper plate 2 and the second discharge upper plate 3. After the hidden air path, the discharge shaft 5 not only serves as a support and positioning structure, but also can avoid using additional air pipes to transmit the air source, effectively saving the table space and facilitating the cleaning work of the staff after production.

[0043] The discharge bottom plate 4 includes a bottom plate main body 41, a partition plate 42, a baffle plate 43, a passage hole 44, and a third shaft hole 45. A partition plate 42 and a third shaft hole 45 are provided on the bottom plate main body 41. The partition plate 42 divides the bottom plate main body 41 into two discharge areas. A plurality of passage holes 44 are provided at the edge position of the bottom plate main body 41, and a baffle plate 43 is provided between two adjacent passage holes 44. At the same time, when the second discharge upper plate 3 and the discharge bottom plate 4 are installed together, one boss 33 corresponds to one passage hole 44, and the boss 33 is provided at an oblique upper position of the passage hole 44. Therefore, during the discharging process, after the capsule enters the passage hole 44, the passage hole 44 can play a guiding role for the capsule, so as to avoid the problem that the capsule is pushed upward and then topples in advance, thereby avoiding the reduction of the corresponding capsule surface area during subsequent blowing and preventing the unstable situation of capsule ejection. In addition, when the finished capsule enters the discharge bottom plate 4, the presence of the baffle plate 43 can prevent the capsule from toppling left and right, and the boss 33 extending downward from the second discharge upper plate 3 behind the capsule can effectively prevent the capsule from toppling backward. In the actual application process, since the plurality of passage holes 44 are not connected, and the diameter of the passage hole 44 is larger than the diameters of all currently commonly used capsule models, the passage hole 44 can not only play an auxiliary guiding role, but also avoid jamming the capsule. After the capsule is pushed in place, the solenoid valve connects to the air source to start blowing. The push rod 10 will stagnate at the highest point and the highest point is higher than the upper surface of the passage hole 44 of the discharge bottom plate 4. The push rod 10 will not immediately fall back, leaving enough time for the capsule to be blown out, thus avoiding the situation of capsule falling back. Since the passage holes 44 are not connected and a baffle plate 43 is provided between two passage holes 44, there is no risk that the capsule is blown into the passage hole 44 and then falls back onto the preparation module 9.

[0044] The top end of the discharge shaft 5 is provided with a thread structure matching the hand-tightening nut 1. During the actual installation of the discharge shaft 5, the top end of the discharge shaft 5 sequentially passes through the third shaft hole 45, the second shaft hole 32, and the first shaft hole 22, and the top end of the discharge shaft 5 will protrude from the upper end face of the first discharge upper plate 2. Then, the top end of the discharge shaft 5 is threadedly connected to the hand-tightening nut 1. Four interconnected air holes 52 are provided at a position near the top end of the discharge shaft 5, which can ensure smooth exhaust at all angles. At the same time, an air path structure 51 is provided inside the discharge shaft 5, and the air path structure 51 is communicated with the air holes 52. When the discharge shaft 5 is installed in place, the air holes 52 provided thereon are exactly located in the second shaft hole 32. Since the second shaft hole 32 is sequentially communicated with the first groove 34, the second groove 35, and the ventilation hole 38, and each ventilation hole 38 is respectively communicated with two air outlets 37, therefore, during the process of supplying air to the discharge shaft 5, the air holes 52 on the side of the discharge shaft 5 can introduce compressed air into the hidden air path formed by the first discharge upper plate 2 and the second discharge upper plate 3. Specifically, the compressed air will enter the second shaft hole 32 from the air holes 52, and then sequentially pass through the first groove 34, the second groove 35, and the ventilation hole 38, and finally the compressed air is horizontally exhausted from the air outlet 37 to blow out the capsules. Preferably, O-ring grooves are respectively provided in the first shaft hole 22 and the second shaft hole 32, and sealing rings 8 are respectively installed in the two O-ring grooves. Such a structure enables seals to exist at both the upper and lower ends of the air holes 52, which can effectively prevent the leakage of compressed air and effectively ensure that there is no air leakage in the discharge shaft 5 within the adjustable height range.

[0045] During the actual working process, before discharging using the capsule discharging device of the present utility model, the empty capsules have completed the processes of capsule sorting and turning, material filling, and capsule cap and body locking through the prior art. The completed finished capsules are placed in the preparation module 9 with the capsule caps facing upwards, and then the push rod 10 pushes the capsules out of the holes of the preparation module 9 and into the through holes 44 of the discharge bottom plate 4. Compressed air enters the hidden air path formed by the first discharge upper plate 2 and the second discharge upper plate 3 through the air holes 52 of the discharge shaft 5, and then is horizontally discharged from the air outlets 37 of the convex platform 33. At this time, the pushed-out capsules just reach the position, and the horizontal compressed air blows down the capsules, and the capsules slide out from the inclined surface of the discharge bottom plate 4, thereby realizing the discharging operation. After the capsules are blown out, they are collected and aggregated through the discharge port 6, which can aggregate the two groups of separately discharged capsules into one place, facilitating subsequent collection and largely avoiding the damage of dust to the workshop environment.

[0046] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
